OLIVER O. BOWEBS, OI CAPE GIRABDEAU, MISSOURI.

MOTOR IPL OWQ Cape Girardeau and State of Missouri, have invented a new and Improved MotorPlow, o'f'which the following is a full, clear, and exact description.

This invention relates to plows and particularly 'to motor plows-and has for an object the provision of an improved arrangement whereby the plo-ws may be mounted in place and used in the usual manner of plows or they may be removed and the re- 5 maining structureused as a motor tractor.-

Another object in view is to'provide a motor plow construction and forming the parts so that one wheel will be in advance of the other so as to cause the plows to plow at an even depth on anuneven surface as well as on an even surface. A still further object in view is to provide a motor plow with a plurality of traction wheels and mechanism for quickly and easily raising and lowering the plows at any time. I

A still further object in view is to provide a motor plow with a tractor construction so formed as to permit of an easy adjustment of one of the traction wheels whereby said wheel may be raised and lowered in its respective frame, thus providing an even horizontal position for the frame when one of the wheels is in a furrow as well as when the device is being moved over a road.

In the accompanying drawings: Figure 1 1s a top plan view of a motor plow embodying the invention; Fig. 2 1s a side view of the structure shown in Fig. 1; Fig. 3 is adetail longitudinal vertical section through Fig. 1, the same being taken on line 33;

Fig. i is a detail fragmentary sectional view 1 on line H;

through Fig.

to the accompanying drawings Referring by numerals, 1 indicates a frame of any suitable kind made from a good quality of metal so as to be amply strong for supporting the various parts. A U-shaped axle 2 is connected w th frame 1 in any suitable manner and is arranged to carry traction wheels 3 and 4: of any suitable size. These traction wheels are preferably provided with claws or cleats 5 so as to readily engage the earth and force the device along when in A swivel-Wheel 6 is arranged at the front of frame 1 and is provided with Specification of Letters Patent.

a bevel gear 7 meshing with gear 8 whereby the wheel 6 may be turned as desired for steering a plow. A rod 9 is connected with bevel gear 8 and is operated by a hand wheel 16 also carries a bevel gear 17 meshing with bevel gear 18. Gear 18 operates the shaft 19 which shaft extends into the casing 20 containing a suitable differential for operating the shafts 21 and 22. These two shafts are mounted in suitable bearings in frame 1 and carry sprockets 23 and 2%, which sproclr-' ets accommodate chains 25 and 26, respectively. Chain 25' passes over a sprocket 2'? rigidly secured to wheel 3, while chain 26 passes over a. sprocket 28 rigidly secured pendently driven.

In order that the wheel 4 may be'raised and lowered as desired sons to allow frame 1 to be horizontal when the wheel is in a furrow, the same is journaled on a suitable axle mounted. in a swinging segment 29, which segment is journaled on shaft 22 and is provided with a rack 30 at the rear, which rack meshes with a worm 31 operated by hand wheel 32. The segment 29' is also pro vided with a slot 33 (Fig. 2) through which a pin 33 passes. This construction provides a guide for the segment while the same is being moved up and down and also assists in holding the segment in place, pin 33 preferably being an extension of the axle 2.

lVith the construction just described the device may be used as a t 'actor on a farm or other place for pulling any desired object- However, the frame 1 and associatedparts are especially adapted for operating plows 3i and Only two plows are shown but it is' evident that the device could be arranged for moving more plows if desired without departing from the spirit of the in vention. The plows are provided with beams 36 and 37, respectively, over which are passed clevices 38 and 89, which clevices are journaled on a shaft it) which shaft also passes through the rear ends of the swings The forward ends of these swings are pivotally mounted on a rod or shaft 43, which shaft is formed by suitable brackets connected with frame 1. The forward end of each of these swings is provided Patented J ly%i, i916. Application filed October 8, 1915. Serial No. 54,785.

to wheel 4, whereby these wheels are indewith a downwardly extending member 44, as shown in Fig. 3. A rod 45 extends through the member 44 on each of the swings and through one of the apertures l6 on the forward end of the respective beams 36 and 37, as shown in Fig. 3. lhe forward bracing bar 47 is connected with beams 36 and 37 so as to properly space the forward ends thereof. A spring 47 connected with the bracing bar l7 and with one end of a bell crank lever 48, which bell crank le- 'ver is pivotally mounted on the axle 2 so that end 49 thereof. may have the link 50 pivotally connected therewith and with rod 40. Bell crank lever 48 is rigidly connected with. shaft 51 which is pivot-ally supported on axle 2 by any suitable lnean as for in stance, brackets. An, operating lever 52 is connected'with shaft 51 so as to move the same back and forth and consequently raise and lower the plows 34c and A locking rack 53 is provided on axle 2 to engage the catch on lever 52, as clearly shownin Figs. 1 and 3, whereby the plows may be locked at any desired height, as for instance in a fully elevated position or fully lowered position. The spring 47 isprovided to counterbalance someof the weight of the plows whereby any one,-as for instance, a boy, may easily operate the lever or handle 52.

In operation, whenthe parts are arranged as shown in the drawings, the device may be "*nSed'as a-motor plow and the plow raised and lowered as desired andalso wheel 4L adusted as desired. It will be observed that Wheel 4 ism advance of wheel 3. This will allow the plows 34 and to be offset in such a manner as to operate properly and to vice as a tractor the plows maybe quickly plow at a substantially even depth on level ground and on uneven ground, Wl'ienever it is desired to remove the plows from the ground lever 52 is grasped and operated or swung forwardly, whereupon the swings 41 and 42 will be raised and the plows therewith. If it should be desired to use the de removed by taking-out the belt or pin 43 and.

the belt or pin 40. The spring 4'1" and assoframe, a clevis for said. swing, said clevis being adapted to surround the beam of said plow adjacent the rear of the beam, and a rod engaging the front of said beam and said swing for connecting the front of the swing with the front of said beam.

2. in a motor plow of the character described, a frame, ail'urality of plows provided with beams, a swing for each of said plows, each of said swings being provided with a clevis overlapping the rear part of said beams, a pin extending through said swings at the front and through said beams, and means acting on said swings for rais ing and lowering the same pivetally, whereby said plows are raised and lowered as desired.

In a deviiiwe of the character described, a frame, a plurality of plows provided with beams, a swing for each of said plows, each of said swings being formed with a long arm extending dmvnwardly, means for pivotally mounting said swings at the juncture of the long arm and the short arm'to said frame, means for connecting the forward end of the beam of each of the plows to .,the respective depending arm of the respective swings, means for connecting the rear end ofthe respective long arms of the beams of the respective plows, and means connected with the rear end of the long arm for rais ing and lowering the swing and. the plow connected therewith.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
